LCT

A gene for lactose tolerance

Lactose tolerance is the ability to digest the lactose in milk and other everyday dairy products. For the majority of people, tolerance for lactose decreases after infancy, often falling away completely during adulthood. However, for others, due to a genetic variant in their DNA, they are able to continue to tolerate lactose indefinitely. Your FitnessGenes result will tell you whether you are genetically able to tolerate lactose.

Milk is for babies. When you grow up you have to drink beer so said bodybuilding icon Arnold Schwarznegger. So was Arnie right? Well, maybe, if you are lactose intolerant.

As babies, with few exceptions, we can all drink milk. Packed full of calcium and protein, it provides us with an excellent source of energy during the rapid growth and development of our infancy. However for some of us, as we get older, our ability to digest milk starts to wane, and dairy consumption starts to produce some uncomfortable side effects, such as bloating, excess wind and stomach cramps.

So what exactly is going on? It’s all down to a sugar found in milk and other dairy products called lactose.
